Ideal if you are starting now with 10 kWh but might add an cargador de VE and bomba de calor in five years.

What else should you look out for?

Don't forget the costes de instalación

The battery price is only part of the investment. For instalación fija systems, costes de instalación of EUR 400-800 are added on top. A backup box for emergency power costs an additional EUR 200-500. Always factor this into your comparison.

Compatibility with your inversor

Always check whether the battery is compatible with your existing inversor. A BYD Battery-Box works with virtually any brand, but a Huawei LUNA 2000 is most efficient with a Huawei inversor. The wrong combination can lead to lost functionality or the need for an additional inversor.

Garantía terms are not equal

Pay attention not just to the duration (years) but also to the capacity garantía. A 10-year garantía with 60% remaining capacity (Huawei, BYD) is less generous than 10 years with 80% remaining capacity (Anker, Tesla). That 20% difference equates to 2 kWh of usable storage on a 10 kWh battery.

Price per cycle

Why price per kWh is not the full picture

The price per kWh is not the full picture. A battery at EUR 300/kWh with 6,000 ciclos is cheaper per cycle than a battery at EUR 250/kWh with 4,000 ciclos. Do the maths:

Price per cycle calculated

Always calculate the total cost over the vida útil, not just the purchase price.

Preguntas frecuentes

Which batería doméstica is the best of 2026?

There is no single "best" batería doméstica. The Anker SOLIX X1 offers the best all-round balance for the average family. The Huawei LUNA 2000 is the most efficient. The EcoFlow DELTA Pro Ultra delivers the best alimentación de respaldo. The Fox ESS ECS2900 is the cheapest. The right choice depends on your priorities.

How much does a batería doméstica cost in 2026?

Prices range from EUR 1,199 for a compact 1 kWh plug & play unit to more than EUR 12,000 for a large instalación fija system. On average, you pay EUR 300-700 per kWh of capacidad de almacenamiento. The price per kWh has dropped by approximately 15-20% in 2025-2026.

Can I combine brands?

In principle, no. A batería doméstica performs best within the ecosystem of one brand. The main exceptions are the BYD Battery-Box and Pylontech Force H2, which are compatible with a wide range of third-party inversors.

How long does a batería doméstica last?

Most baterías domésticas last 15-25 years with daily use. LFP cells gradually lose capacity: after 6,000 ciclos (approximately 16 years), a good battery still has 80% or more of its original capacity. Zendure even claims more than 8,000 ciclos for their silicon-carbon packs.

Is a batería doméstica safe?

Yes. All baterías domésticas in this comparison use LFP technology (lithium iron phosphate), which is thermally very stable. LFP has no thermal runaway risk like older NMC chemistry. All systems comply with EU safety standards (IEC 62619, UN38.3).

When is the right time to buy?

Now is an excellent time. Battery prices are at historic lows, devolución del IVAs are still available, and the compensación neta scheme ends on 1 January 2027. The longer you wait, the more net-metered revenue you miss out on. Moreover, lead times and installation waiting times are increasing as 2027 approaches.
